2-way SMS using SMPP

[Maciej Pigulski]

Does anyone have any informations how to send 2-way messages using
SMPP?

I guess that it is somehow done using TLV parameters but I couldn't
find any reliable info about it. Any informations appreciated.

It's something like that:
- sms is sent to an end user from an standalone application (a
question for example)
- end user chooses reply on that message and types in some "text" and
sends the message back
- standalone application receives the message from the user and is
able to connect this message with the sms that was sent earlier

with this model we have a conversation between the standalone
application and a user

this is what Jsmpp does in term of sending/receiving SMS (there are examples how to send and receive SMS in the downlioad area) but the logic of the service you want to implement you need to develope it by your self

Hm, it is more advanced then simple send and receive because it is about connecting sent message with received message so you have a conversation.

When you send 10000 sms different messages and 5000 users will reply to some of this messages how would you know which reply is the answer for which message?

Of course it can be done with some weird application logic that requires an "id" to be passed in the message body that user is replying with but I believe that there are more sophisticated methods based on SMPP protocol to provide this functionality.

you may need to give to each question asked an Id in the body of the text message and the user should reply with text as "Id+ answer" in that case you will know that answer is belong to the question Id.


in other way in the SMSC you may have what we called routing range (LogicaCMG SMSC does) let's say you have a short code 8000 from your local operator you can ask to configure in the SMSC a routing range from 80000000 till 80009999 as example so your question may be sent with source address a number from the range you have let's say 8001111 and the user will just reply to 8001111 the SMSC will know to route that number to short code 8000 then you will receive it in your application then from the destination address you will know the response is belong to witch question

Hope it helps
